After the heat pump is finished installing and debugging by professional technician, the users should read the manual carefully and can operate the heat pump via the controller.

By controller, the users can select running mode, adjust water temperature, set the clock time, set ON/OFF timer, check running state and check failure code, etc. For parameter adjusting, it should be done only by professional person when it is necessary.

When the heat pump is cut off power supply and it will last for some period, the users should drain away all the system water to avoid frost crack in winter. And when restart it again, should check the system thoroughly.

Any maintenance work should be carried out by qualified technician. For common failures, they can refer to the failure code table for troubleshooting.
